unable to slice

Recommended Posts

Cura 2.4 on Windows 10. Using the Printrbot Play with heated bed. I've imported the standard Play Getting Started PLA profile from printrbot.com (it's a 15.04-style .ini file). This is the very first time I'm trying 2.4, I've just installed it.

I've tried to load an STL file I made a while ago. That STL works great with 15.04.6 and the Getting Started profile and I've printed it twice with 15.04.6. But on 2.4 I get the error:

Unable to slice with the current settings. The following settings have errors: Prime Tower X Position, Initial Layer Height, Raft Base Thickness, Prime Tower Y Position

What's wrong and how can I fix it?

Oh, and maybe I'm blind but I can't seem to find a way to attach the STL and INI files to this post. That's weird. Anyway, here are the files:

First, cura 2.4 is a totally new program, build from ground up, don't use any 15xx files, plugins etc, will not work.

Then, for the sake of curiosity (only own Ultimakers) I had a look at the PLAY setup.

I see there is at least a printer definition available, so that's nice, but it does not seem a very refined one...

I see by default all visibility settings are turned on, even the ones you definitely don't need, like for dual extrusion, so you probably want to clean this up.

Also the standard profiles are weird;

"normal" is 0.2 and "low" is 0.15 - does not make any sense...

If you want to change the base setup of the machine you'll find the machine definition here; C:\Program Files\Cura 2.4\resources\definitions

And most of the base settings can be changed in a menu in the machine settings.

I guess your quickest solution would be to get some profiles and a project file from someone who already tweaked cura for the PLAY (is there no printrbot forum?) else you'll just have to do some trial and error yourself....

We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
